About NetBSD/i386

NetBSD/i386 is the port of NetBSD to generic machines ("PC clones") with 32-bit x86-family processors. It runs on PCI-Express, PCI, and CardBus systems, as well as older hardware with PCMCIA, VL-bus, EISA, MCA, and ISA (AT-bus) interfaces, with or without math coprocessors.

Any i486 or better CPU should work - genuine Intel or a compatible such as Cyrix, AMD, or NexGen.

NetBSD/i386 was the original port of NetBSD, and was initially released as NetBSD 0.8 in 1993.
